We use the UEC hot-dip galvanizing process, which is the most advanced and widely used method in the world.
The main product specifications range from 0.20–0.80mm thickness and 800–1250mm width.
We can produce high-performance galvanized iron (GI) with high zinc coating. Options include non-spangle, minimal spangle, regular spangle, or large spangle, along with advanced processing such as oiling or skin-passing.
This product is suitable for use in building materials and electrical appliances.
Characteristics
The surface of the galvanized sheet is smooth, free of zinc slag and burrs, and has a silver-white appearance.
The zinc coating thickness is precisely controlled and can be adjusted according to customer requirements.
Excellent welding and forming performance.
Strong corrosion resistance — products can pass a 96-hour salt spray test.
Packaging & Shipping
Standard Wooden Pallet & Woven Bag Packaging
Stainless steel sheets are covered with wooden plates for protection during transportation.
All stainless steel sheets are securely loaded in strong wooden packaging.
Each carton is properly shored and reinforced for stability.
Transportation is fast, and customers are kept informed at every step.
